Insulin pump having a food database

Abstract

A method for calculating a meal bolus in an insulin pump and an insulin pump are disclosed. The insulin pump includes a pump mechanism and a memory configured to store a plurality of food entries in a food database. The insulin pump also includes a programmable circuit arranged to control the pump mechanism and operatively connected to the memory. The programmable circuit is programmed to accept entry of one or more food entries into the food database. The programmable circuit is also programmed to associate each of the one or more food entries with a carbohydrate value. The programmable circuit is programmed to prompt selection of one or more food entries. The programmable circuit is further programmed to calculate a meal bolus based on the one or more food entries.

       14. The insulin pump of  claim 1 , wherein the programmable circuit is further programmed to prompt a user to input a serving size of the food entry. 
     
     
       15. The insulin pump of  claim 14 , wherein the programmable circuit is further programmed to limit the serving size based on a maximum deliverable meal bolus. 
     
     
       16. The insulin pump of  claim 1 , wherein the programmable circuit is further programmed to associate nutritional information with each of the one or more food entries. 
     
     
       17. The insulin pump of  claim 16 , wherein the nutritional information includes at least one of fiber, fat, or protein information. 
     
     
       18. The insulin pump of  claim 1 , wherein the programmable circuit is further programmed to, upon determination of nutritional information, transmit a message to the user, the message regarding food or insulin intake. 
     
     
       19. The insulin pump of  claim 18 , wherein the message includes one or more recommendations regarding timing and amount of meal consumption. 
     
     
       20. The insulin pump of  claim 18 , wherein the message includes one or more recommendations regarding timing and amount of bolus delivery. 
     
     
       21. The insulin pump of  claim 18 , wherein the nutritional information includes a glycemic index. 
     
     
       22. The insulin pump of  claim 1 , wherein the food entries comprise meals consumed by the user.
